Gary Kremen (born 1963) is an American engineer and entrepreneur who invented online dating, founded the personals site Match.com, was the first registrant of Sex.com and founder of Clean Power Finance, and is the current chair of the Santa Clara Valley Water District. Since 1993, Kremen has been a private and angel Investor in over 50 companies (individually or through venture capital funds), of which several have gone public or had liquidity events.
Born in the Chicago area, he graduated from Niles West High School in 1981 and then graduated with bachelor's degrees in electrical engineering and computer science from Northwestern University in 1985 and an MBA from Stanford University in 1989.

In 1993, Kremen founded Electric Classifieds, Inc. Funded by private investors in November 1994, he launched the online personals service Match.com in April 1995.

Over Kremen's objections, Match.com was sold to Cendant Corporation for $7 million in 1998 and sold by Cendant to Ticketmaster a year and a half later for $50 million.
From 1995 to 1996, Kremen co-founded and served as president of NetAngels.com, Inc., an Internet profiling and personalization company that suggested web sites to users. He left after 3 months.

Sex.com legal caseEdit
Kremen first registered the domain name sex.com in 1994 as well as jobs.com, housing.com, and autos.com. In 1996, Stephen M. Cohen contacted Network Solutions and fraudulently had the domain transferred to his name. Kremen sued Cohen for the return of the sex.com domain name. As Cohen had profited from sex.com while assigned to him, Kremen was awarded a judgment of $65 million against Cohen. Cohen fled to Mexico and moved the money offshore. Kremen obtained Cohen's Rancho Santa Fe mansion, to which he relocated after the court case resolved. In 2003, Kremen successfully litigated against Network Solutions. On October 28, 2005, the Los Angeles Times reported Cohen had been arrested in Mexico and turned over to US authorities. Kremen sold sex.com in 2006 to Boston-based Escom LLC for $15 million in cash and stock, and sold sex.net for $454,500 later that year.
